Biscayne Bay recorded 430 reported boating accidents from 2009 to 2023 in the U.S. Coast Guard's data, with 33 deaths and 282 injuries.
The pattern that sets it apart is collision with recreational vessel (40% of accidents, 1.5x the statewide rate). Read the reports and the same threads keep surfacing: hit-and-run departures (7% of reports, 1.6x the state rate) and anchoring (16% of reports). Below is what happens on Biscayne Bay, in what conditions, and how to stay out of the count.
Every figure below comes from the U.S. Coast Guard's Boating Accident Report Database for this water body. No two produce the same pattern.
Annual reports have stayed roughly flat across the 15 years, ranging from 18 to 41.
Signature event: collision with recreational vessel (40%).
Recurring circumstances coded from the 430 narratives.
26% occur June–August; 62% on weekends, peaking Sundays.
Its fatal-accident rate of 6% sits below both Florida's 9% and the 14% national average, the profile of a place with more minor incidents than catastrophic ones. Alcohol was a factor in 5% of accidents here against a 7% national average. The one contributing cause that stands out from the usual operator-error codes is machinery failure, tied to 9% of accidents.

40% of accidents (collision with recreational vessel) are collisions with another boat, the most preventable category. One person cannot both drive and watch on busy water. Assign a lookout, keep right, and slow where traffic converges.
46% of the reports here (197 accidents) involve striking a fixed object like a dock, bridge, piling, or seawall. Approach structures at idle, account for current setting you sideways, and never cut a blind turn near a bridge.
7% of the reports here (29 accidents, 1.6x the statewide rate) here were hit-and-run. Florida law requires you to stop and help. A collision you report is a citation; one you flee is a felony.
16% of the reports here (67 accidents) mention anchoring. Set the hook with enough scope, never anchor by the stern in current or swell, and keep an anchor watch as conditions build.
Drowning accounts for 10 of the deaths recorded here, and 100% of those victims were not wearing a life jacket. A life jacket only works worn. Florida requires every child under 6 to wear one on a vessel under 26 feet underway, and one wearable PFD for every person aboard.
In Florida, anyone born on or after January 1, 1988 must complete an approved boater safety course and carry a Boating Safety Education ID Card, plus a photo ID, to operate a vessel powered by 10 HP or more. The legal limit for boating under the influence is 0.08 BAC.
